Abstract

Building upon the highly successful Phase I simulations and experimental verification, the proposed Phase II program will develop a high-efficiency single-mode vertical-cavity surface-emitting lase (VCSEL) emitting at 1.3 micron wavelengths. Such VCSELs are highly sought after in the general areas of fiber communications (short-to-mid-distance telecom) and gas sensing. The Phase II program will iteratively designed improved single-mode VCSELs aided by a rigorous electromagnetic simulation program, then fabricate and test the VCSELs. Part of each iteration will be to compare the simulated and experimental results in order to better interpret the simulation results. The goal is to produce a 1.3 micron single-mode VCSEL having at least 1mV output power at temperatures up to 85 degrees C. The Phase II Option Program calls for fabrication of the VCSELs using a Picolight-developed manufacturable oxidation process. The 1.3 micron VCSELs are targeted for ise in fiber optic transmitters for campuses, military bases, ships and metropolitan networks. Similar VCSELs emitting at 1.4 or 1.6 microns will be used for monitoring gasses such as carbon monoxide of carbon dioxide.
